Answer:
Explanation:
The statement is expressed as
y
∝
1
x
inverse means
1
variable
To convert to an equation introduce k, the constant of variation.
y
=
k
×
1
x
⇒
y
=
k
x
To find k use the given condition that y = 8 when x = 4
8
=
k
4
⇒
k
=
4
×
8
=
32
⇒
equation is

The area for a rectangle is length × width.
The area for a parallelogram is base × height.
The area for a trapezoid is height (base 1 + base 2) ÷ 2. The area for a rhombus is base × height.
Hope this helps^^ :)
(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
